Electrified replacement method for secondary wiring terminal strip of transformer substation

The invention discloses an electrified replacement method for a secondary wiring terminal strip of a transformer substation. The method comprises: firstly, carrying out correct bypass drainage on the terminal strip by using a bypass drainage tool, then, clamping a lead on one side of the terminal strip by using an insulated wire clamping tool, and simultaneously, loosening a fastening screw by using an insulated screwdriver to loosen a metal head of the lead; then pulling out the wires and sleeving the metal head with an insulating rubber cap, then dismantling the wires on the other side of the terminal strip by using the same method, then taking down the terminal strip from the guide rail by using an insulating clamp and installing a new terminal strip, and then respectively connecting the two dismantled wires to the new terminal strip; and then, using a universal meter for measuring whether the through-flow of the new terminal strip is normal or not, if the through-flow is abnormal, checking the insertion d
